Software Engineer - Simulation & Flight Systems

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. SOFTWARE ENGINEER – SIMULATION & FLIGHT SYSTEMS As a Software Engineer in Special Programs, you’ll design, develop, and own critical software that powers the exploration and validation of next-generation technologies across every SpaceX flight system. You’ll take full ownership of new features in a scalable, high-performance application that spans the entire design–build–test–operations pipeline, while also contributing to critical control and flight system software. Your work will directly expand our capabilities in both ground and space systems and help prove out the innovations that make multiplanetary life possible. This is a high-impact role where you’ll collaborate across engineering teams to build a high-throughput distributed system that develops and demonstrates cutting-edge software and hardware. The systems you create will be used by engineers pushing the limits of what’s possible—your code will help fly rockets, test vehicles, and shape the future of spaceflight. Aerospace experience is not required. We’re looking for exceptionally smart, motivated software engineers who thrive on complex challenges, move fast in dynamic environments, and care deeply about software craftsmanship. Our software is mission-critical, and we have no shortage of hard, interesting problems that demand creative, high-quality solutions. RESPONSIBILITIES: Rapidly develop prototypes that prove key design concepts and quantify technical constraints Develop high-performance modules for real-time flight systems data streaming Contribute to test automation processes and CI/CD infrastructure Create and maintain high-fidelity simulation and flight software for all vehicles Continually raise the bar for excellenc
